VENTILATOE.

Apphcation filed August 4, 1928.

This invention relates to a ventilator designed and adapted to be used in conjunction with a window for the purpose of allowing fresh air to enter a room or apartment, and to exclude rain and other elements of weather, when the window is open.

Some of the objects of the invention are: to produce a ventilator of the indicated Character which will be of simplified and durable construction; one which may be readily at tached; one which prevents forceful blasts of air from entering a room or apartment, and which divides the air in such a manner as to prevent drafts; and one which may be manufactured with comparative economy.

The nature of the invention and its distinguishing features and advantages will appear when the following specification is read in connection with the accompanying drawing, in which- Figure 1 is a vertical sectional view through a ventilator constructed in accordance with the invention, and applied to a window frame, a portion of which is shown, and also showing a portion of a lower sash in open position.

Fig. 2 is a sectional plan view, the section being taken on the line 2-2 of Fig. 1, portions of the wlndow frame being shown, and

away.

Fig. 3 is a plan view of a blank from which the ventilator shown in Figs. 1 and 2 is produced, an intermediate portion of the blank being broken away.

In Figs. 1 and 3 inclusive there has been shown one form of ventilator constructed in accordance with the invention. On reference to Fig. 3 it will be apparent that a blank 10 is produced from a single piece of sheet metal. This blank 10 is so stamped and cut, that when folded or bent along the line 11 produces a section 12, which will be the main section, and a section 13 having perforations l l which will be the top section. lVhen the section 12 is bent along the lines 15, the opposite ends respectively of the section 12 will be provided with side flanges 16, and by bending said section 12 on the line 17, a flange may be produced along the lower edge of the section 12, said flange which is designated 18 may be rolled. W hen the top section 13 is bent along the line 19, said section will be provided with a depending flange 20. By banding the top section 13 Serial No. 297,483.

along the lines 21, depending flanges 22 are provided respectively at the opposite ends of said top section 13. By bending the top section along the lines 23 there will he presented depending slotted lugs 24 respectively on the opposite ends of the top section 13. It will be observed that the top section 13 is also provided with corner notches 25. The flanges 22 on the top section 13 respectively overlap the side flanges 16 on the main section 12. In this manner a ventilator is produced which is ready for use in. conjunction with a window.

In order to apply the ventilator use is made of two fastening elements such as the screws 26 which are screwed into the stops 27 respectively on the side stiles of the Window frame. The slotted lugs 24 may then be engaged respectively with the screws 26, it being understood that the screws 26 will be so positioned that the roll flange 18 will. be in contact with the sill and stops. It will also be apparent that the notches respectively accommodate the steps 27. ()n reference to Fig. 1, it will be apparent that when the lower window sash 28 is open, that air will be deflected upwardly through the perforations 14C in the top section 13, by the main section 12 which serves as a baffle. It will also be apparent that rain and other elements of weather will be excluded by the perforated top section 13. Furthermore forceful blasts of air will be prevented from entering a room or apartment by the top section 13, and the perforations 1 1- will divide the air into streams to thus eliminate drafts.

The flanges 1S and 20 give strength and rigidity to the main section 12 and the top section 13 respectively, supplemented by the flanges 16 and 22 respectively on the sections 12 and 13, which have a similar effect, and the latter flanges also prevent air and the elements of weather from passing around the opposite ends of the deflector section 12, particularly in cases where the side stiles of the window frame are relatively narrow in wardly from the sash stops, and in cases where it is desired to omit the notches 25, though attachment is made to the sash stops respectively on the side stiles of the window frame. In such cases, screws or studs will be placed respectively on the stops of the frame near the sill thereof, to prevent the ventilator from shifting to a position in which it would being closed.

I claim: p

1 A ventilator stamped, bent and formed from a single piece of sheet metal to provide a main deflector section, a perforated top section on the upper edge of the deflector section, which extends the entire length thereof, and slotted lugs respectively on the opposite ends of the top section for the purpose of attaching the ventilator.

2. A ventilator made of sheet metal and consisting of a main deflector or bailie section, a perforated top section extending laterally from the upper edge of the deflector section, said top section being equal in length to the deflector section, and provided prevent the Window sash With corner notches and slotted lugs respectively on the opposite ends thereof.

3. A ventilator made of sheet material and consisting of a main deflector or bafile section, and a perforated top section extending laterally from the upper edge of the main section, said main section having a curled lower edge, and angular flanges respectively on the opposite ends; the top sect1on having angular flanges respectively on the opposite ends, a depending flange on its longitudinal edge, corner notches, and slotted lugs respectively on the opposite ends disposed at said notches; the end flanges on the top section respectively overlapping the end flanges on said main section.
